Implement proxy contract for blockchain integrations

[xilosada]

Integrating a Calimero context with a blockchain is currently challenging. We’ve heard from developers who have experienced difficulties in implementing blockchain integrations. The goal of this proposal is to simplify and streamline this process by introducing a more robust and context-aware proxy contract system.

Goals

• Enable secure and context-specific proposal creation and approval.
• Support optional member and permission management through integration with the configuration contract.
• Facilitate automated proposal execution upon receiving sufficient peer approvals.
• Enhance governance and control by limiting active proposals and managing peer-specific permissions.

Tasks

• Implement automated execution of proposals once they reach the required number of approvals.
• Add functionality to register the proxy contract in the configuration for managing members and permissions.
• Set limits on total active proposals and the number of proposals each peer can create.
